SPECIFICATION forming part of Letters'rstentno. 704,710, dated July 15, 1902. I

Application filed March 27. 1,902# Serial No. 100,322. (No'model.) l

To all wiz/m it may concern:

Be it known that I, EDWARD F. SHnLnA- BERGER,of Dekalb, Illinois,have invented certain new and useful Improvements in Barbed- Wf@ Machines, of which the following is a'Y specification.

erated, which will apply a double-'pointed barb to a strand-wire and twist a Ifellow wire therewith and upon the barb.

The leading feature of the machine consists in such a construction, arrangement, and 'or-4 ganization of the parts as will permit the twister-spindle which forms the barb to travell forwardly with the travel of the strand-Wires during the formation ofthe barb, and thereby avoid any loss of 'time in the application of This is accomplished by providing a sliding bed which vis caused to advance in the direction of the travel of the strand-wires the barb.

. during the formation of the barb and to retract after the barb is formed.

The particular rfeatures which I considerV to be new and desire to secure byLetters Patent relate tothe means for driving the spindle and for holding the same against any ret-,

rograde movement, whereby the twister-pin carried by the spindle is always maintained in proper position for the twisting operation.

' This spindle driving and controlling mechanism is' also combined and associated'with other elements of the machine, so that they table carrying the twister-spindle is moved.l

in proper time and the spindle itself is guide and cushioned in a novel manner.` i'

My invention will be hereinafter morefully described and particularly pointed-out in the claims. f`

InA the accompanying drawings l have shown in Figures 1 to 8,'inclusiv'e,I the preferred form of construction and in Figs. 9 and 10 a slightlymodified construction.

In said drawings, Fig. 1 is a plan View of the machine complete eXcept-as-to certain portionsof the spooling mechanism, which gearing for driving thespindle and the means forfactuating the table and feed mechanism for the wire from which the barbs are formed. Figli is a transverse sectional view taken on about theline 4 et 4of Fig. 2 looking in the directionfof'the arrow t. Fig. 5 isV on the sameA line,butloolzingin the opposite direction. (See Aarrow 5.) "Figs.6,7,'and 8 are details, Fig.

6 showing a' plan view of the spindle with its tip in section, theend of the knifeor shear and ,the barbed-wire stock fed across the strandwire, and showing its relation to thecoilingpin. Fig.: 7 shows the forni ofthe barb as applied to' the strand-wires; Fig.- 8 is a view taken at right angles to the axis of the spindle,

showingthe relation of the barbed wire to the v pin and the shearing-knife. Fig. 9'is a plan view of a' modiiedform of the machine in.

which the Yspindle is driven by an interrupted or mutilated gear instead of a rack, as in the former views, and' showing also a diiierent Ameans for actuating the cut-0E or knife. Fig; 10 vis a partiallongitudnal sectional elevation'of Athe machineshown in Fig. 9. Many of the partsof this machine are old and of well-known construction, and no particular description need be given thereof.

The machine as a whole may be mounted ,upon a' frame orstandll and the operative parts -driven 'throughthe power-shaft 12,

from which the power is transmitted through the bevel-gears 1314to2shaft '15 and thence through the sprocket-chain 16"to shaft 1'7. Shaft 17 ,throughthe bevel-gears 18 19, drives a short shaft20, parallel to the power-shaft 12, and shaft 2G, lthrou'ghvthepinion 21 and gearl 22 and pinion 23l and large gear 24, drives the feedwheels 25 26,'whioh feed in :the strand-wires??28.*A These wires are conducted forw'ar'dlythrough suitable guides, thewire 27 passing through the hollow axis of the spindle 291 a rotary and a sliding movement within a bearing 30and itis driven throughthelinstrumentality ofa sleeve 3l, with whichit Said' spindle 29I has .both i has a slot-and-key connection, the slots being vmarked 32 and the keys 33; The sleeve 3l has a bearing in the standard 34: and carries a gear'35, driven by a lpinion 36, mounted loosely on the shaft 37,-which'latter has a' bearing in thestandard 34C and'also in a vstandard 38 and has secured thereon the gear ICO 39 and a clutch member 40. The clutch member 40 has a spring locking-pin or clutchdog 4l and normally contacts the face of the gear 36. The latter has a cam-lug 42 thereon, with a square shoulder or face and a sloping side, so that in one direction it will engage with the clutch-pin 4l and lock the clutch 40 and the gear 36 together, while permitting the independent movement of the clutch in one direction of rotation. The gear 36 is locked against retrograde movement by means of a spring-actuated locking-pin 43, mounted in a standard 34, which isl adapted to engage an aperture 44 in the side of the gear 36, the web of the gear being cut away or beveled, as shown at 45, to enable the pin to slide out of locking engagement with the gear during its movement in one direction.

A rack 46 is enmeshed with the gear 39 and has a vertical reciprocating motion imparted to it through the pitman 47, driven from a wrist-pin 48 on lthe crank-wheel 49, which is mounted on a short shaft 50 in the hanger 5l, and said shaft carries on its opposite end'a gear 52, driven by the gear 53 on the shaft 17. The bearing is mounted upon a sliding table 54, which slides in ways on a frame ll and carries thereon the feed mechanism for the barbed-wire stock and also the knife for shearing the barb from the barb-wire stock, which reciprocating movement is imparted to said table through the eccentric 55 on shaft 20 and pitman 56, the forward end of thel pitman being pivotally connected to a lug 57 on table 54. The parts are so proportioned and timed that the table performs its forward traverse during two revolutions of the spindle. The barbs are formed from a wire 58, which is fed forward by a pair of feed-wheels 59 60; but as the means for driving this feed mechanism are old no particular description thereof is necessary. The wire 58 is fed beneath the strand-wire 57 in front of the nose of the spindle, and the latter has a pin 61,.

which engages beneath the endof the lbarbwire and coils it about the strand-wire 27 in an obvious manner. The coils of the barb are formed while the bed is being moved forward,and the travel of the bed is proportioned, of course, to the speed of the spindle and the movement of the strand-wires forward.

A spring 62 is coiled around the spindle and has a bearing upon a collar 63 thereon and also upon a bearing 30. This permits the spindle to yield longitudinally while holding it in proper relation to the forming-barb.

Describing the operations of the parts thus farA enumerated, the rack 46 is given a regular-.reciprocating motion. On its upstroke it turns the gear 39, but does not move the gear .36, the latter being held during the upstroke of the rack by the pin 43. On the downward stroke of the rack the clutch members 4l and 42 are in driving engagement and rotate the gear 36, the pin 43 sliding out of locking engagement therewith. During the downward movement of the rack oneco'mplete revolution of the gear 36 occurs, and this effects two revolutions of the gear 35, connected with the arbor or sleeve member 3l of a spindle 29. The pin on the spindle gives the double coil to the barb, and the spindle itself slides forward with the table as the coiling of the barb progresses. At the completion of the forward stroke a knife 64, carried by knife-block 65, is actuated to sever the barb from the wire 58. The knife-block has an arm 66, which contacts with a xed lug 67. on the frame at the end of the forward movement of the table, and thus rocking movement is imparted to the block for actuating the knife.

From the foregoing description itwill be observed that the rack which drives the spindle is always in engagement with the gear and that the clutch mechanism is a simple automatic mechanism. The operation of these parts is smooth, without jar or shock, and entails but little wear, and the machine performs its work with such certainty that it rarely misses a barb, while its capacity is great.

I have not described the spooling mechanism, although its position is indicated and parts of it are shown in Fig. l of the drawings.

In Figs. 9 and l0 I have shown a slight modiication of the means for driving the spindle, the operation of this modified apparatus being substantially the same. Instead of the rack I have shown a mutilated gear 68, which engages a bevel-gear 69 on the sleeve 3l, and the gear, although slightly different, is essentially the same. The knife-block in this construction has an elongated body portion 70, which catches over a latch 7l, pivoted on the frame, so as to rock the knife-block at the end of the forward movement of the table.

I Claim-+- 1. In a barbed-wire machine the combination with a stationary frame, a table mounted to slide upon said frame, bearings yon the frame and the table respectively, and a twopart spindle, one part of which is mounted in the bearing on the frame and the other in the bearing on the table, a driving-gear iXed on the non-sliding member of the spindle, means for sliding the table and gearing for imparting an intermittent rotary motion to the two-part spindle, substantially as described.
